Explain how one can rate the closeness of related organisms by comparing dna base sequences

1 answer:

6 0

Scientists believe we all originated from one common ancestor. using our dna base sequences, we can determine how closely related organisms by looking at when the first differing sequence occurs. for example, U U T A you can determine that
U U T T 1 and 2 are more
U U A T closely related than 1 and 3 because their dna sequence stays the same for longer. hope this helps :)

Question:

Trudy made this Venn diagram comparing interphase and cytokinesis.

Which statement belongs in the region marked X? (image attached)

Answer options:

Is the longest stage
DNA is copied
The number of nuclei doubles
The number of cells doubles

Answer:

The number of cells doubles

Explanation:

Cytokinesis describes the splitting of the cytoplasm after mitosis. During interphase, the DNA is replicated. During mitosis, the DNA condenses into chromosomes, and the chromosomes are aligned and separated to opposite ends of the cell. During cytokinesis, the cell separates into two daughter cells.

The longmenshan fault is in china. This fault was created when two tectonic plates collided with each other, resulting in the rise of mountains next to the sichuan basin. This fault is most likely a reverse fault.

A reverse fault is a fault that exists in areas that are undergoing compression in which the rock on top of the fault plane is moved upward relative to the rock under the fault plane. A reverse fault is completely different from normal faults and it reduces the faulted section of rock.
